Tips on identifying make/mfg?

[MD427]

Hello All. I've got a car and I'd like to figure out who made it, as it needs some TLC, but as i go though it I don't know much about what I'm looking at. Also I'm just curious. Anyway, if i could determine the kit mfg/assembler it might at least be a starting point.

Things I know: It has a 427FE Sideoiler. It has a CSX Plate/VIN, but it doesn't match any "real" chassis number series (original or continuation), so I think the builder just made it up. Fiberglass body. 6 speed Trans.

Things I think I know: Built in the early 90's. I was told it uses a Jaguar suspension. Looking underneath there are 2 struts on each rear control arms... that is one standout unique feature I can see for sure. Wheels are real spinners, I've been told 'real' magnesium.

Does this information give me any real clue as to who might have originally built it? What other identifying features I should look for that could tell me? There is nothing obvious on any visible surface regarding branding or serial numbers or production lot codes. Other than the apparently fake Shelby American, Inc badge.
